1. Field of the Invention

This invention relates, generally, to purse or bag hangers. More specifically, it relates to a purse or bag hanger capable of removably securing a bag to a structure, such as a post, or any vertical or horizontal surface.

2. Brief Description of the Prior Art

Carriers of purses, handbags, and any other personal accessory having handles rarely have a suitable location for storing their bags when in public places. Those who carry bags often have to choose whether to place their bags on a tabletop, on a chair back, in their laps, or on the ground. Tabletops typically are limited in surface area, chair backs are out of sight, laps are uncomfortable, and the ground is unsanitary. In all cases, lack of a secure and reliable method for retention renders the aforementioned devices susceptible to damaging impact with surfaces, theft and soiling.

Attempts have been made to overcome these problems; however, they have obvious disadvantages. Most bag hangers, such as U.S. Pat. No. 8,371,546 B2 to Bauerly, use friction to keep the hanger set on the table or surface. These devices can easily slip off the table or surface when the bag or hanger is accidentally contacted. Additionally, these devices provide no security from potential thieves.

Other devices, such as U.S. Pat. No. 2,920,369 A to Zezula, use a suspension clamp to hang a bag from a surface. Such devices are still susceptible to theft because the clamping force is released when the tension, supplied by the weight of the bag, is relieved upon lifting the bag.

Accordingly, what is needed is a bag hanging device capable of being removably secured to a surface without the possibility of becoming accidentally detached from the surface or purposefully stolen. It is also recognized that there is a need for a device that allows secure attachment to surfaces of orientations other than horizontal such as vertical walls or chair backs. However, in view of the art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the field of this invention how the shortcomings of the prior art could be overcome.

All referenced publications are incorporated herein by reference in their entirety. Furthermore, where a definition or use of a term in a reference, which is incorporated by reference herein, is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.

While certain aspects of conventional technologies have been discussed to facilitate disclosure of the invention, Applicants in no way disclaim these technical aspects, and it is contemplated that the claimed invention may encompass one or more of the conventional technical aspects discussed herein.

The present invention may address one or more of the problems and deficiencies of the prior art discussed above. However, it is contemplated that the invention may prove useful in addressing other problems and deficiencies in a number of technical areas. Therefore, the claimed invention should not necessarily be construed as limited to addressing any of the particular problems or deficiencies discussed herein.

In this specification, where a document, act or item of knowledge is referred to or discussed, this reference or discussion is not an admission that the document, act or item of knowledge or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge, or otherwise constitutes prior art under the applicable statutory provisions; or is known to be relevant to an attempt to solve any problem with which this specification is concerned.

The long-standing but heretofore unfulfilled need for an improved bag-hanging device is now met by a new, useful, and nonobvious invention.

The novel structure includes a first retention arm and a second retention arm, where each retention arm has a first end and a second end creating a length. The first ends are connected to a mechanism housing and the second ends are connected to contacting surfaces. The retention arms have a shape such that there are only two possible points of contact creating an open receiving space. One point of contact is at the mechanism housing and the other point of contact is the contacting surfaces.

The retention arms are capable of rotating with respect to each other about a pivoting axis. The pivoting axis runs through the mechanism housing in close proximity to the first end of the retention arms. The retention arms have an open position and a closed position, where in the closed position the contacting surfaces of the first retention arm and the second retention arm are in close proximity and in the open position the contacting surface of the first retention arm and the second retention arm are at a distance apart that is greater than the distance between the contacting surfaces in the closed position.

The mechanism housing contains a locking mechanism having an engaged setting and a disengaged setting. In the engaged setting, the locking mechanism prevents the retention arms from rotating towards the open position and in the disengaged setting, the locking mechanism allows the retention arms to rotate towards the open position. The first and second retention arms form an outer perimeter when in the closed position and the mechanism housing is located within the outer perimeter.

The present invention also includes a release button having a first position and a second position and in communication with the locking mechanism. When in the first position, the release button places the locking mechanism in the engaged setting and when in the second position, the release button places the locking mechanism in the disengaged setting. A biasing component is in communication with the release button such that transitioning from the first position to the second position requires overcoming a biasing force imposed on the release button by the biasing component.

In a certain embodiment, the locking mechanism is a ratchet mechanism having a first ratchet component and a second ratchet component such that the two ratchet components are contacting each other when in the locking mechanism is in the engaged setting. The first ratchet component is in communication with the first retention arm such that rotation of the first retention arm results in rotation of the first ratchet component and the second ratchet component is in communication with the second retention arm such that rotation of the second retention arm results in rotation of the second ratchet component. The second ratchet component is also in communication with the biasing component and the release button, so that biasing force forces the second ratchet component towards the first ratchet component, which in turn forces the release button to the first position. The biasing force is of a predetermined magnitude such that an external force applied to the release button may overcome the biasing force to urge the release button to the second position and transfer the external force to the second ratchet component resulting in the first and second ratchet components separating to place the locking mechanism is in the disengaged setting.

In another embodiment, the locking mechanism is a cam assembly having a cam bearing, a cam release, and a cam bearing mount. The cam release includes wedges in communication with cam bearing wedge receipts and cam release wedge receipts and the cam release is in communication with the release button. The cam bearing is rotationally mounted on the cam bearing mount, such that the cam bearing is capable of rotating with respect to the cam bearing mount. The cam bearing is also in communication with second retention arm, such that the cam bearing is subjected to a moment of force attempting to rotate the cam bearing with respect to the second retention arm.

Additionally, this embodiment includes the first retention arm having a cylindrical extension with an inner diameter and a length such that at least some portion of the cam bearing is encircled by the inner diameter of the cylindrical extension. The cylindrical extension has a central longitudinal axis and the cam bearing has a rotational axis where the two axes are not longitudinally aligned. This orientation allows for the cam bearing to frictionally secure the cylindrical extension when rotated. The disengaged setting includes the cam release and wedges forced towards the cam bearing mount, by the release button overcoming the biasing force of the biasing component to transition the release button to the second position. This movement overcomes the moment of force and aligns the cam bearing wedge receipts with the cam release wedge receipts. The alignment of cam bearing wedge receipts and the cam release wedge receipts results in the cam bearing oriented within the cylindrical extension such that the cam bearing is not in a frictionally securing contact with the cylindrical extension. The engaged setting includes the cam release, wedges, and release button forced away from the cam bearing mount, by the biasing force of the biasing component, leaving only a portion of the wedges in communication with the cam bearing wedge receipts and the cam release wedge receipts. The moment of force causes the cam bearing to rotate so that the cam bearing wedge receipts and the cam release wedge receipts are no longer aligned and so that the cam bearing is in frictionally securing contact with the cylindrical extension.

In a certain embodiment, the present invention includes a wireless communication module capable of communicating with a mobile device. In a certain embodiment, the bag clamp has a visual alert and/or an audible alert. Both alerts may be synced with a mobile device through the wireless communication module.

In a certain embodiment, one or both of the connections between the contacting surfaces and the retention arms are pivoting connections.

A certain embodiment includes an alternate orientation attachment having an open receiving space that is generally perpendicular to the open receiving space of the bag clamp.

A certain embodiment has a strap retention feature originating near one end of one of the retention arms within the outer perimeter of the arms creating a gap, of a predetermined distance between the one retention arm and the strap retention feature that is adapted to receive a bag's straps.

A certain embodiment includes a secondary locking mechanism having an engaged setting at a predetermined amount of rotation about the pivoting axis, which prevents the arms from rotating an amount greater than the predetermined amount of rotation.

In a certain embodiment, the present invention includes a mechanical lock having a locked position and an unlocked position, where the locked position prevents the locking mechanism from moving to the disengaged setting.

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part thereof, and within which are shown by way of illustration specific embodiments by which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention.

Biasing Component: is an object applying a force to a structural component.

Frictionally Securing Contact: is a contact between to surfaces that prevents movement of the two surfaces with respect to each other based on friction force.

Moment of Force: is a tendency to cause rotation about a specific axis.

Open Receiving Space: is the open space between the retention arms.

Ratcheting Mechanism: is a device having a bar or wheel with a set of teeth in which a pawl, cog, or tooth engages to allow motion in only one direction.

Release Button: is any mechanism having a first biased position and a second urged position.

Visual Alert: is an observable and identifiable change to the bag clamp.

The present invention is a bag clamp having at least two coaxial retention arms, capable of rotating about a pivoting axis between an open and closed position. Each retention arm is connected to a mechanism housing that has an ability to lock and release the retention arms at various degrees of rotation about the pivoting axis. Each retention arm has a first end and a second end creating a length between the two ends. The first end is connected to the mechanism housing and the second end is connected to a contacting surface. In a certain embodiment, the contacting surface has a cross-section greater than the cross-section of the retention arm creating a hook like feature extending towards the first end of the retention arm. In a certain embodiment, the contacting surfaces are made of a material having a high coefficient of friction and/or have surface features that increase the coefficient of friction. The coefficient of friction of the contacting surface is predetermined to overcome the forces acting on the bag clamp that are attributed to a bag, of a predetermined weight, hanging from the clamp. In a certain embodiment, the present invention includes end caps on the contacting surfaces, which improve the coefficient of friction, protect the surface to which the clamp is secured, and elastically deform to allow for greater clamping force. The end caps can be fixed or removably attached to the contacting surfaces/retention arms as is known to a person having ordinary skill in the art. The end caps are made of any material, known to a person having ordinary skill in the art, capable of elastically deforming, preferably elastically deforming before the retention arms.

The length of the retention arms extends outwards in a generally radial direction with respect to the pivoting axis. When in the fully closed position, the retention arms have two possible points of contact—the mechanism housing and contacting surfaces, such that the bag clamp has an outer perimeter and an open receiving space formed by the two retention arms. The mechanism housing is preferably located inside of the outer perimeter, towards the open receiving space. Additionally, the mechanism housing includes a locking mechanism to allow the retention arms to lock at generally any degree of pivot with respect to the pivoting axis. The retention arms are released from a locked position by a release button. The release button has a first biased position and a second urged position. The second urged position is achieved by overcoming the biasing force on the release button. The locking mechanism transitions between the disengaged setting and engaged setting as the release button transitions between the first biased position and the second urged position.

The disengaged setting of the locking mechanism allows the retention arms to rotate with respect to each other. The engaged setting prevents the retention arms from moving to a more open position. In a certain embodiment, the engaged setting allows the retention arms to rotate from an open position to a more closed position. The locking mechanism may be any device known to a person having ordinary skill in the art, such that the device has a setting preventing the retention arms from rotating towards the open position, such as a pawl and ratchet wheel. In a certain embodiment, the clamp may be subjected to a rotational bias in conjunction with the locking mechanism or may be subjected to a rotational bias without a locking mechanism, such that the rotational bias is forcing the clamp towards the closed position.

As shown in FIG. 1, a certain embodiment of the present invention, generally denoted by reference numeral 100, includes two coaxial retention arms—first retention arm 102 and second retention arm 104. First retention arm 102 has first end 106 and second end 108. Similarly, second retention arm 104 has first end 110 and second end 112. First ends 106 and 110 of the two retention arms are connected to mechanism housing 114. Second ends 108 and 112 are connected to contacting surfaces 116 and 118, respectively. The contacting surfaces 116 and 118 have a surface area larger than the cross-section of retention arms 102 and 104. Additionally, contacting surfaces 116 and 118 extend towards first ends 106 and 110, respectively, creating a hook like feature.

Retention arms 102 and 104 each have a shape such that the two retention arms have only two possible points of contact creating open receiving space 120. The two possible points of contact include mechanism housing 114 and contacting surfaces 116 and 118. Open receiving space 120 receives bag straps 122 (two straps are shown) along with a surface or structure that the clamp is intended to be secured (See FIG. 10).

Mechanism housing 114 includes release button 124 centrally located about the pivoting axis of mechanism housing 114. However, release button 124 may be located anywhere on the bag clamp as is known to a person having ordinary skill in the art. Release button 124 is shown in a first biased position. Release button 124 is under a biasing force and has a second urged position achievable when an external force, usually created by a user, overcomes the biasing force. The second urged position (See FIG. 9) is achieved when release button 124 is compressed into mechanism housing 114.

The mechanism housing includes a locking mechanism, which has an engaged setting and a disengaged setting. The engaged setting prevents retention arms 102 and 104 from rotating towards the open position and the disengaged setting allows retention arms 102 and 104 to rotate towards the open position. As shown in the exploded views of FIGS. 12-14, the mechanism housing is made up of two halves—first half 113 and second half 115. First retention arm 102 is connected to first half 113 and second retention arm 104 is connected to second half 115. First half 113 has semi-circular coupling feature 117 that extends towards second half 115 and has groove 119. Second half 115 has circular coupling feature 121 that extends towards first half 113, has groove 123, and has a radius greater than coupling feature 117. The two halves 113 and 115 are joined by aligning grooves 119 and 123 and inserting C-shaped clamping feature 125 into grooves 119 and 123. Clamping feature 125 has a thickness such that there is an inner surface and an outer surface, where the inner surface has a radius generally the same as the radius of groove 119 and the outer surface has a radius generally the same as groove 123. Clamping feature 125 is therefore able to maintain the alignment of grooves 119 and 123 while also allowing the two halves 113 and 115 to rotate with respect to each other. Additionally, clamping feature 125 has a C-shape with a circumference greater than a half circle to enable clamping feature to hold the two halves 113 and 115 together. Furthermore, clamping feature 125 is made of a material having a predetermined Young's modulus such that it can plastically deform around the mechanism housing and return to its original shape when set into grooves 119 and 123.

FIGS. 12-14 also provide a certain embodiment of the locking mechanism referred to as a ratcheting mechanism. The ratcheting mechanism includes first ratchet component 126 connected to first half 113, which is in turn connected to first retention arm 102. Additionally, the ratcheting mechanism includes second ratchet component 128 coupled to second half 115, which is connected to second retention arm 104. Second ratchet component 128 is constrained from rotation about the radial axis but is allowed to articulate along the radial axis of component 115 when the button component 124 is actuated. In a certain embodiment, the ratchet components can be fixedly or temporarily attached to the mechanism housing through any method known to a person having ordinary skill in the art, so long as the ratcheting components rotate along with the respective halves of the mechanism housing upon which they are attached.

Moreover, the locking mechanism includes biasing component 130, which forces second ratchet component 128 towards first ratchet component 126 such that the teeth of the two ratchet components 126 and 128 are capable of contacting each other (See FIG. 12c). As shown in FIG. 12c, the teeth have a shape and orientation such that ratchet components 126 and 128 may rotate with respect to each other in a single direction (towards the closed position) while in the engaged setting. FIGS. 12-14 show biasing component 130 between second ratchet component 128 and second half 115, however, biasing component 130 may be located anywhere known to a person having ordinary skill in the art such that it forces second ratchet component 128 towards first ratchet component 126.

FIGS. 12-14 also show that release button 124 is in contact with second ratchet component 128 when fully assembled and therefore release button 124 is capable of altering the locking mechanism between the engaged and the disengaged setting. The engaged setting is achieved when release button 124 is in the first biased position. The disengaged setting is achieved when release button 124 is in the second urged position forcing second ratchet component 128 to overcome the biasing force created by biasing component 130. FIG. 12c provides an example of ratchet components 126 and 128 in close enough proximity to qualify as an engaged setting, however, the components may be located at a closer proximity while in the engaged setting.

As shown in FIG. 15, a certain embodiment of the present invention may include contacting surface 116 having a pivoting connection to retention arm 102. In a certain embodiment, both of the contacting surfaces may be pivotally connected to the retention arms to allow the contacting surfaces to sit flush with the object being clamped no matter the degree of pivot at which the retention arms are oriented. By enabling the entire contacting surface to sit flush with the object, the contacting surface is able to exercise the maximum clamping and therefore friction force available. If the embodiment has a single pivoting contacting surface, the contacting surface would preferably be attached to the arm intended to sit on top of the surface. This consideration allows the contacting surface of the bottom arm to act as a hook to prevent the bag's straps from falling in case the retention arms rapidly move to a fully open position. In the embodiment having two pivotally connected contacting surfaces, the contacting surfaces may have a limited range of pivot. The limited range of pivot of the contacting surface would improve the friction force capabilities of the clamp while also allowing the contacting surfaces to act as hooks for catching a bag's straps when the arms rapidly move to a fully open position.

As shown in FIG. 16, a certain embodiment of the present invention includes strap retention feature 132 to aid in preventing an inadvertent dropping of the bag upon actuation of the release button. Strap retention feature 132 may be any shape known to a person having ordinary skill in the art and may originate from the mechanism housing as shown in FIG. 16. In a certain embodiment, strap retention feature 132 may originate from the second end of second retention arm 104, or may originate from any location known to a person having ordinary skill in the art such that the straps will be retained if the clamp were to suddenly open to a fully open position. Strap retention feature 132 may be on either or both retention arms 102 and/or 104.

As shown in FIG. 17, the bag clamp may include alternate orientation attachment 134 to alter the orientation of the hanging bag so that the bag's length is generally parallel with bag clamp's retention arms 102 and 104. Alternate orientation attachment 134 may have any known shape so long as alternate orientation attachment 134 is adapted to receive or to connect to one of the retention arms of the bag clamp. Additionally, alternate orientation attachment 134 is preferably capable of opening and locking shut to receive the straps of a bag. Alternate orientation attachment 134 may be fixed or removably attached to any portion of the bag clamp as is known to a person having ordinary skill in the art.

In a certain embodiment, the bag clamp may include visual alert 136 exemplified by rays of light expelled through release button 124, as shown in FIG. 18. Such an embodiment would include a transparent release button or a transparent portion of the release button with a lighting device located inside of the mechanism housing at a distance from the outer surface of the button such that the light created from the lighting device passes through the transparent button or transparent portion of the button. The visual alert may perform any function known to a person having ordinary skill in the art. The visual alert is preferably in communication with the bag clamp's power source (not shown) to notify the user that the power source needs to be replaced or recharged. Additionally, the visual alert may be in communication with a wireless communication module (not shown), such as Bluetooth, to wirelessly connect to the owner's mobile device. The visual alert would relay any notifications that have occurred or are occurring on the owner's mobile device. The visual alert may use any visual effects known to a person having ordinary skill in the art.

As shown in FIG. 19, a certain embodiment of the present invention includes audible alert 138, illustrated by sound waves, to alert the owner that an unauthorized attempt has been made to actuate the release button on the clamp. The audible alert is preferably located in retention arm 102, however, it may be located anywhere on the bag clamp, such as the release button or mechanism housing. In this embodiment, the bag clamp may require a specific procedure for unlocking the clamp and the security warning would be activated upon a failure to execute that specific procedure. Additionally, the bag clamp may include an accelerometer that activates the security warning when the bag clamp is forcefully removed from a surface while the clamp is in a locked position. Further considered security measures include a GPS tracking device and a remote activation for the audible alert. These features are considered for tracking down a bag that was previously lost or stolen. In a certain embodiment, the audible alert could be linked to a user's mobile device similar to the visual alert to provide an audible alert to any notifications experienced on the mobile device.

The electrical components, wireless communication module, and power source required in certain embodiments are preferably stored inside the mechanism housing. However, they may be stored in the arms to prevent increasing the size of the mechanism housing.

In a certain embodiment, as shown in FIG. 20 and generally denoted by reference numeral 200, the two halves of the mechanism housing 213 and 215 are coupled using flexible couplings 217 that extends towards second half 215. Each flexible coupling 217 has a first resting position and a second flexed position along with a distal end that includes an angled flange. Second half 215 includes an internal rim (shown in FIG. 23 as reference numeral 319) on which the flange of flexible coupling 217, 317 rests when halves 213 and 215 are coupled. The internal rim extends around the internal circumference, or a portion thereof, of second half 215 to allow the arms to rotate with respect to each other while coupled. Second half 215 also includes access 225 allowing an object to be inserted into second half 215 and force flexible coupling 217 into a flexed position when the two are aligned. Flexible coupling 217 is capable of flexing an amount to disengage the flange from the internal rim such that first half 213 may separate from second half 215. In this embodiment, there are two flexible couplings and two accesses, which are capable of simultaneous alignment. In a certain embodiment, there may be any number of flexible couplings and accesses as is known to a person having ordinary skill in the art. Additionally, a certain embodiment may have a flexible access that is capable of disengaging the flange from the rim without the need of an additional object to be inserted into an access.

FIGS. 21-25 illustrate another embodiment having a locking mechanism in the form of a cam assembly. The cam assembly includes cam bearing 340, cam release 342, cam spring 344, cam bearing mount 346, and cam spring platform 348. Cam bearing mount 346 and cam spring platform 348 are secured in second half 315 of the mechanism housing. Cam bearing mount 346 is adapted to support cam bearing 340, which contains a through hole adapted to receive cam bearing mount 346. Cam spring platform 348 is adapted to receive and support one end of cam spring 344. The other end of cam spring 344 is in communication with cam bearing 340. Cam bearing 340 preferably includes overhang 345 extending outward from the outer surface of cam bearing 340 in the radial direction. Overhang 345 includes an insert for receiving cam spring 344.

As shown in FIG. 21, cam bearing 340 has an outer surface of a generally circular shape, excluding the overhang, and a corresponding central longitudinal axis. The through hole has central longitudinal axis that is offset from the central longitudinal axis corresponding to the outer surface. Cam bearing 340 rotates about the central longitudinal axis of the through hole (hereinafter rotational axis) to create an eccentric or off-center rotation. In a certain embodiment, the cam bearing has an ovoid shape to increase the effects of the off-center rotation. The rotational axis is preferably aligned with the rotational axes of the arms and the longitudinal axes of release button 324 and cam release 342, however the alignment is not necessary. The off-center through hole results in some portion of the outer surface of cam bearing 340 being a greater distance from the rotational axis than other portions of the outer surface of cam bearing 340.

Illustrated in FIG. 22 cam release 342 is in communication with biasing component 330 and release button 324. Biasing component 330 is also in communication with second half 315 and is applying a biasing force on cam release 342 to force it away from second half 315, which in turn forces release button 324 away from second half 315. Cam release 342 includes two angled wedges 343 having a predetermined length. Both cam bearing 340 and cam bearing mount 346 include corresponding wedge receipts 350. When the bag clamp is assembled, at least some portion of wedges 343 are in communication with corresponding wedge receipts 350 to prevent excessive rotation. Wedges 343 are angled and wedge receipts 350 are beveled such that cam bearing 340 rotates into alignment, illustrated by arrow 360, as cam release 342 is forced towards second half 315, illustrated by arrow 365 The same features of wedges 343 and wedge receipts 350, allow cam bearing 340 to rotate slightly when wedges 343 are only partially received by wedge receipts 350. The rotation is the result of cam spring 344 exerting a spring force on cam spring platform 348 and overhang 345 creating a moment about the rotational axis.

As shown in FIGS. 21, 23, and 25, first half 313 of the mechanism housing includes cylindrical extension 352 adapted for receipt by second half 315. Cylindrical extension 352 has a central longitudinal axis out of alignment with the rotational axis of cam bearing 340. Moreover, cylindrical extension 352 has an inner diameter of a size such that the outer circumference of cam bearing 340 does not frictionally secure cylindrical extension 352 when cam release 342 is forced towards second half 315 such that wedges 343 align wedge receipts 350. Additionally, the inner diameter of cylindrical extension 352 has a size such that cam bearing 340 frictionally secures cylindrical extension 352 when cam release 342 is forced away from second half 315 such that wedges 343 remain only partially inserted into wedge receipts 350 and cam spring 344 rotates cam bearing 340.

The cam assembly is in a disengaged setting when release button 324 is forced towards second half 315, in turn forcing cam release 342 towards second half 315 to overcome the biasing force exerted by biasing component 330. As release button 324 moves towards second half 315, wedges 343 on cam release 342 further penetrate wedge receipts 350. The wedge shapes of wedges 343 cause wedge receipts 350 to align and cam bearing 340 rotates to overcome the moment being exerted by cam spring 344. The orientation of cam bearing 340 when rotated to align wedge receipts 350 is such that cam bearing 340 is no longer in a frictionally securing contact with cylindrical extension 352. The two halves 313, 315 and their respective arms are free to rotate with respect to each other and the cam assembly is considered to be disengaged.

The cam assembly is in an engaged setting when biasing component 330 forces cam release 343, and in turn release button 324, away from second half 315. As a result, wedges 343 remain only partially inserted into wedge receipts 350 and cam bearing 340 is forced to rotate due to the moment created by cam spring 344. The wedge or angled shape of wedges 343 allow wedges 343 to remain partially inserted into wedge receipts 350 while also allowing cam bearing 340 to rotate. Cam bearing 340 is only capable of rotating a limited number of degrees, about eleven degrees, which is based on the width of the wedges and the width of the wedge receipts. Cam bearing 340 only needs to rotate an amount such that cam bearing 340 can achieve a frictionally securing contact with cylindrical extension 352. The off-center rotation shape causes the cam bearing to jam into the cylindrical extension after small degree of rotation to prevent the two arms from rotating with respect on one another. The prevention of rotation is referred to as the engaged setting. In a certain embodiment, the cam bearing may be in contact with the cylindrical extension without frictionally securing the cam bearing, due to the contact being minimal.

In a certain embodiment, there may be any number of wedges and corresponding wedge receipts. Additionally, the shape of the cam bearing, width of the wedge receipts, and the shape of the wedges can be altered as is known to a person having ordinary skill in the art such that the cam assembly has both an engaged and a disengaged setting. In a certain embodiment, the cam release and release button may be a single structure.

In a certain embodiment, the bag clamp includes a secondary locking mechanism designed to release the clamp in stages rather than completely disengaging the ratchet so that the arms rotate to the fully open position. This feature prevents the clamp from quickly opening to the fully open position where the bag is at a higher risk of losing contact with the bottom retention arm of the clamp and falling to the ground. In a certain embodiment, the secondary locking mechanism is simply two structural elements that come in contact at a predetermined degree of rotation towards the fully open position. Similar to FIG. 20, such an embodiment may include access 225 on first half 213 capable of receiving a pin. The pin has a length such that the pin encounters a structural element attached to second half 215, such as flexible coupling 217, to prevent further rotation of the two halves with respect to one another. One of the structural elements may have a first biased position and a second urged position such that in the biased position, the two structural elements will contact each other at the predetermined degree of rotation towards the fully open position. When the one structural element is in the urged position, the two structural elements are not capable of contacting each other and the arms may rotate to the fully open position. The secondary locking mechanism may be achieved through any combination of structural components known to a person having ordinary skill in the art.

In a certain embodiment, the bag clamp includes a mechanical lock that must be released before the release button can be actuated. The mechanical lock may include a removable feature preventing the actuation of the release button until the removable feature is replaced or the mechanical lock may require that the removable feature be removed to release the button. The mechanical lock and removable feature, such as a lock and key, respectively, may be any lock and any feature that is known to a person having ordinary skill in the art.

In a certain embodiment, the bag clamp includes a spring mechanism creating an opening force on the two arms. This allows the mechanism to go, unaided to the open position upon the actuation of the release button.

In a certain embodiment, the bag clamp may be any size and shape known to a person having ordinary skill in the art such that there are at least two retention arms capable of alternating between an open and closed position and such that there exists an open receiving space between retention arms while in the closed position. Additionally, the bag clamp may be used for any function known to a person having ordinary skill in the art, such as a temporarily clamping two objects together.

The advantages set forth above, and those made apparent from the foregoing description, are efficiently attained. Since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matters contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention that, as a matter of language, might be said to fall therebetween.
